Tumbler not rotating, metal on metal smell - Kenmore 67632 Electric Dryer

In all likelihood, the belt that runs the tumbler is loose, causing the tumbler to rotate off center. While it takes a few minutes, the front of the dryer should be removable and you can take the tumbler out and replace the belt.

E4 Tumbler rotation failure If during a cycle the tumbler rotational speed drops to 0, all outputs will be turned off and error code E4 will be displayed.

Removal & Installation

Before servicing any vehicle, please be sure to read the precautions section, which deals with personal safety, prevention of component damage, and important points to take into consideration when servicing a motor vehicle.

WARNING Vehicle must be in PARK prior to ignition cylinder removal.

1. Disconnect the negative battery cable.
2. Disable the SIR (air bag) system, as outlined in the Chassis Electrical Section.
3. Remove the steering column trim covers.
4. Insert key into the ignition and rotate to the RUN position. Then rotate ignition cylinder back to ACC position.
5. Depress the locking button through hole on side of ignition module assembly with a thin pick-type tool then slide the lock cylinder from the ignition housing.

To install:

NOTE If you are installing a new lock cylinder, recoding will be required and a J 41340, Lock Cylinder Holding Fixture and Staking Tool will be required.

NOTE Ignition lock cylinder reads key cut position 1 through 9.

1. Insert the appropriate tumbler (3) according to the key code into the corresponding tumbler ward.

2. The tumblers will not immediately seat into position because the sidebar has been pre-assembled. The tumblers will have to be pushed past the sidebar with a small flat screwdriver or pocket knife.
3. The tumbler springs (2) should then be inserted into the spring wells in the cylinder (4) where they will sit on top of the tumblers.
4. The seal plate (1) will be installed and crimped.
5. Insert the seal plate locator legs into the receptacle slots in the cylinder--seal plate will seat into position only when the two locator legs have been properly inserted into the receptacles on the cylinder.
6. While holding the seal plate in position with the thumb, insert the key into the cylinder and watch for the side bar to drop. If the side bar does not drop, the lock is tumbled wrong and you need to start over.
7. Ensure that the side bar does not drop on an angle. The side bar must be completely flush to the cylinder diameter.
8. Stake (1) the two metal areas of the cylinder (2) directly over the seal plate legs with a hammer and punch or chisel.

9. Repeat this stake on the areas of the cylinder directly opposite of the first to stakes.
   NOTE Actuator blade within the ignition module must be in ACC position to install the lock cylinder assembly. If rotated, reposition the actuator blade to the ACC position using needle nose pliers.
   
10. Insert key into ignition lock cylinder and install the cylinder into the lock housing.
11. Rotate the lock cylinder in the housing. Verify proper rotation.
12. Install the steering column trim covers.
13. Enable the SIR system.
14. Connect the negative battery cable.

I need more details but typically a dryer will make a rhythmic rattling noise when loose change and other small metallic objects as well as buttons become trapped in the tumbler impellers (those wing shaped things in dryers).
Loosen and remove the top of your dryer.
Rotate your drum, taking care not to rotate it the wrong way. The right direction of rotation will produce friction to the belt, the wrong direction will cause slack on the belt on one side or the other of the drum.
Rotate the drum until the back side of the impeller is directly on top with the outer screws facing you at the top of the dryer. Remove the screws and pull out the impeller and you will find your noise makers. Do this with the remaining impellers and reinstall.

All dryers have to have a way of allowing the tumbler (that's the thing you put the clothes in) to turn freely, not all of them are the same tho,some use bearings, some use slides,others use rollers. Over time these rollers will need to be oiled,the slides will get thin and start metal to metal contact causing a noise, The rear bearings will then start to make their way to china and cause the tumbler to rub into the heating element and OUCH! These things will cause the motor to prematurely DIE! Its best to examine the dryers, rollers, and slides when you first hear the noise, but who does?

One of the retaining rings on the motor clamp/drum bearing assembly had probably broken, the machine must be taken apart to access to the motor/bearing assembly and fix the part.
The job should be done by a technician.

Using the machine in this condition can cause more damage to motor/ drum bearings.

Here is the diagram.

here you can buy the parts.

You quite possibly have something like a penny or a paper clip stuck at the heat duct. ***First-shut off the electric to the dryer***. From behind the dryer, remove the heat tunnel and clean it out. You will be surprised how much lint gets past the filter. It's an easy repair, just a few screws. While you're back there, look around for any buildup in other areas.

this may help

Due to the nature of security devices, there is no "magic unlock" code for the Defcon device. To recover a lost combination:

·Set the tumblers to the last known combination.

·While applying pressure to the red release button, rotate the tumblers up one digit and then down one digit on each of the individual tumblers.

·For Example: If your last know combination was 565

1.Set the tumblers to 565

2.Hold the red release button in and rotate the 1st tumbler to 6 so that the combination is now set to 665 (If this is the set combination the red release button will move in)

3.Hold the red release button in and rotate the 1st tumbler to 4 so that the combination is now set to 465

4.If not found move onto the 2nd tumbler and repeat step 1-3

5.If not found move onto the 3rd tumbler and repeat step 1-3

soulnds like the belt pooped, or broke, remove top you should see the belt wrapped around the drum, if not you need a new one
